Can someone explain crash tests to me?

I love reading all the technical discussions on here, but Im pretty clueless about all of it :eek:

They only test at 30mph?

Do they test more than one spot on the bench (outboard or center)?

What about the rfing tests? They dont have to test a dummy over 22lbs but the seat can be used IRL up to how many ever pounds the manufacture says it can??

Like I said, I have no idea how any of it all works or even if Im reading things Ive seen posted correctly :confused::eek::confused:

They only test at 30 mph, which is equivalent to something more forceful than the majority of real-life crashes. Real crashes generally happen at a lower speed (even if you're going faster, there's usually braking involved), and the cars are made to absorb some of the force. In crash tests, the entire force is on the seat/occupant.

Frontal crash simulations are the only ones conducted, so there's no difference in seating position.

As for dummy usage, I'm not entirely clear on that, and I it might have changed recently. Pixels or someone else with more knowledge will have to address that because I don't feel like looking it up.

If car A is traveling at 55 mph and gets rearended by car B traveling at 75 mph, then it's a 20mph crash, the difference between the two speeds. For a head on, you add them together, so car A at 10mph hits car b at 20mph, that's a 30mph crash and that's more serious than the first scenario even though the cars were traveling at slower speeds. Seats are tested to 30mph because <I forget exact wording> above that isn't really considered survivable OR up to 30mph is usually survivable, something like that. The majority of crashes are under 30mph the way the vehicles collide. It's unlikely to have a crash at 65mph, even though you drive that speed a lot more often than you go 30, because you're more likely to hit a moving object on the highway than a brick wall. That's my understanding. My high school physics is a little rusty! :)
